I would advise anyone who wants to delve deeply into the origins of grapes to look at ‘Wine Grapes’ by Jancis Robinson et al., the most authoritative tome on the subject. It did help my spinning head a little, but not much, as the Traminer/Savagnin family is more complex than the Ewings of Dallas. Roter Traminer is the same wine as Savagnin Rouge, related to the Gelber Traminer (Savagnin Blanc/Heida) and to Gewürztraminer.
Roter Traminer is the predominant Traminer variety in Austria. It has low acidity and literally does smell (and taste) of roses along with dried fruit, marshmallows and citrus notes. In colour it ranges from intensely green to intensely yellow or even a glisten of red. When produced from ripe grapes, it produces wines with pronounced aromas that age well.
